Green Glow from Ancient Galaxies Surprises Scientists

The galaxies are greener on the other side of the universe, it seems: A new analysis reveals that some of the most distant galaxies ever observed are radiating green light, a finding that could deeply affect developing models of those early galaxies. Researchers have seen this same kind of green light coming from a few galaxies in the nearby universe, but, according to Malkin, the "shocking" part of the new analysis is in the number of galaxies involved: The green light that researchers observed in the new study appears to be coming from most or all of the galaxies that formed in the first 1 billion or 2 billion years of the universe.
